How to Unlock Corona Mountain in Super Mario Sunshine
To unlock Corona Mountain, players must beat the Shadow Mario boss fights in each of the game’s seven worlds. In other words, start and complete the seventh level in each of the game’s seven worlds.
Upon doing this, Mario will return to Delfino Plaza to find it’s now underwater, but the door leading to Corona Mountain will be open.
At this point, all you need to do is walk on through the door to Corona Mountain and the level will be loaded up for you. Alongside the final boss battle you’ll need to beat in order to complete Super Mario Sunshine, you’ll also find a handful of blue coins you can add to your collection.
There’s no way you can possibly miss unlocking Corona Mountain in Super Mario Sunshine, as long as you’re planning to finish the game. You don’t need to have collected a certain number of Shines or Blue Coins for the level to unlock. Simply beat Shadow Mario seven times and the way to the final boss battle will open up before you.
